Did you know?
WebAnswer (1 of 2): There are 3 protons (so obviously 3 electrons) and 4 neutrons. Lithium-7 is the most abundant form of lithium. Lithium-6, which has only 3 neutrons makes up less … Big Bang nucleosynthesis began roughly about 20 seconds after the big bang, when the universe had cooled sufficiently to allow deuterium nuclei to survive disruption by high-energy photons. (Note that the neutron–proton freeze-out time was earlier). This time is essentially independent of dark matter content, since the universe was highly radiation dominated until much later, and this d…

WebThe total number of neutrons in the nucleus of an atom is called the neutron number of the atom and is given the symbol N. Neutron number plus atomic number equals atomic mass number: N+Z=A. The difference between the neutron number and the atomic number is known as the neutron excess: D = N – Z = A – 2Z. flowy satin shortsWeb6 mrt. 2024 · To find the number of neutrons, you will need to subtract the atomic number from the atomic mass.
